Abstract:Beginning in January, 1997, an evaluation process was undertaken by the Maine Department of
Transportation (MDOT) in an effort to determine if developing technologies in the winter
maintenance field might be viable and cost effective additions to MDOT's current fleet of snow
fighting equipment. This process included the evaluation of the following equipment: Case-Tyler
Zero Velocity System, Swenson Precision Placement System, Compu-Spread Ground Speed
Control System and the Dickey-john Ground Speed Control System.
Data collected in both field and controlled settings indicate a savings in material is possible when
utilizing some form of material metering equipment.
Testing performed for purposes of material placement using Zero Velocity and Precision
Placement systems also shows promise in producing material savings.
Realization of these savings will require a significant commitment to equipment calibration and
maintenance. It will also require a high level of coordination and cooperation between all
personnel involved.
In addition to the equipment evaluation, this report briefly discusses the Department's experience
with salt as a primary material for treating highways in winter related conditions.
